Coordinator of Elections Mark Goins said polling places are open despite power outages Tuesday morning in some areas of Middle and East Tennessee. He said paper ballots are available at those locations.

Polls open at different hours across the state, but all will close by 8 p.m.

A new poll indicates that the race between U.S. Rep Marsha Blackburn and former Tennessee Governor Phil Bredesen is really going to come down to the wire.

East Tennessee State University released a new poll on Friday, showing both candidates at 44 percent.

The poll also shows men are more likely to support Blackburn, whereas women are leaning more towards Bredesen. Bredesen is also more popular among independents and millennials – two groups that experts say could make a big difference in many of the elections nationwide.

Both candidates continued to hit the campaign trail hard, with President Trump stumping for Blackburn Sunday night in Chattanooga. She has similar views on the president's policies, from immigration to spending and taxes.

Bredesen, on the other hand, has been critical of the president's border wall plans and has spoken out against his statements on the migrant caravan. He will be hosting several "Get Out the Vote" events across the state today, with stops in Clarksville and Nashville.

The Senate race has broken previous Tennessee spending records, hitting a whopping $85 million so far.

In the Tennessee Governor’s race, the poll has Republican businessman Bill Lee at 48 percent, with former Nashville Mayor Karl Dean at 36 percent.

Both Lee and Bredesen cast their votes Tuesday morning. Blackburn voted last week, while Dean voted on October 24.
